Does a video show Ismail Haniyeh, the chairman of Hamas' Political Bureau, expressing gratitude to Iran for giving Hamas money and weapons after the attack on Israel on October 7, 2023? No, that's not true: The video was made in 2021, and thus predates the Hamas attack on October 7, 2023.
The claim appeared in a video (archived here) on TikTok by @aoos1100 on November 1, 2023, with overlay text (translated from Arabic to English by Lead Stories staff) reading:
Ismail Haniyeh thanks Iran ❤️. Their leader expresses gratitude to Iran publicly.
